UNASSIGNED: Hardware prominence is one of the major established complications following volar plating of distal radius fractures. In particular, dorsal prominence of screws is the leading risk factor associated with post-surgical extensor pollicis longus (EPL) tendon rupture. Although there are many descriptions of attritional EPL ruptures in the literature, concomitant presentation of attritional EPL and extensor digitorum communis (EDC) ruptures following volar plating of distal radius fractures are minimal.
UNASSIGNED: We present a case of concomitant rupture of the EPL and occult rupture of the EDC to the index finger following volar plating of the distal radius. This was discovered intraoperatively and complicated the proposed tendon transfer reconstruction.
UNASSIGNED: Locked volar plate fixation has become the preferred technique for surgical management of distal radius fractures. The complication of multiple extensor tendon ruptures is rare but nevertheless may be encountered. We discuss strategies for diagnosis, treatment, and prevention. Surgeons should be aware of and prepared to proceed with alternative reconstructive procedures if this complication is discovered.

Many conditions are known to cause chronic wrist pain, one of which is accessory muscles which can be easily overlooked as the cause of pain. Here we present a case of chronic wrist pain in a 33-year-old male who presented with painful dorsal unilateral right-hand swelling associated with increased activity. This patient was referred to the radiology department and was found to have an accessory muscle along the dorsal aspect of the wrist consistent with the extensor digitorum brevis manus muscle. The report includes the clinical presentation, radiologic findings, and management.

Entrapment of the extensor indicis proprius (EIP) after open reduction and internal fixation (ORIF) of the distal ulna with a plate and screw construct is rare. By literature review, we found evidence of such complication associated with distal radius fracture, but no past reports relating to the distal ulna. ORIF of the distal ulna is a common procedure for both fracture treatment and deformity correction. Due to the EIP muscle originating primarily from the dorsoradial surface of the distal ulna and the adjacent interosseous membrane, the muscle may be damaged or compressed by a fixation plate during ORIF, resulting in entrapment. We present two case reports of this rare complication, describing the method of clinical diagnosis, surgical treatment, and outcome. Our accompanying cadaver dissection provides an explanation for proper plate positioning during ORIF of the ulna to reduce the risk of EIP entrapment.
